了Centos7.4服務器安裝apache

本文實例講述了Centos7.4服務器安裝apache及安裝過程出現的問題解決方法。分享給你們供你們參考，具體以下：

1、安裝httpd

1. 安裝以前，先查看系統中是否存在已經安裝了的httpd.rpm包，若是，沒有就是沒安裝，有的話rpm -e 對應的rpm包名進行刪除

?

1	#rpm -qa | grep httpd

2. 使用yum安裝(自動安裝依賴包),簡單方便

?

1	#yum -y install httpd

3. 安裝成功後，httpd-v 查看安裝的apache版本，查找apache的配置文件位置

?

1	#find / -name "httpd.conf"

4. 將找到的源配置文件備份一份，防止錯誤後沒法恢復

?

1	#cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.bak

5. 啓動Apache服務

?

1	#systemctl start httpd.service

6. 開機自動啓動Apache服務

?

1 2	#systemctl enable httpd.service 開機自啓httpd #systemctl disable httpd.service 開機不啓動httpd

7. 查看httpd的狀態

?

1	#systemctl status httpd.service

2、安裝過程出現的問題

1. Apache啓動失敗，Job for httpd.service failed because the control process exited with error code. See 「systemctl status httpd.service」 and 「journalctl -xe」 for details

執行命令,查看報錯提示

?

1	#systemctl status httpd.service

問題是80端口被佔用

解決辦法：

查看80端口的使用狀況

① .netstat -lnp|grep 80

tcp        0      0 192.168.180.68:61027        0.0.0.0:*                   LISTEN      6289/oproxyd
tcp        0      0 :::80                       :::*                        LISTEN      846/httpd
tcp        0      0 ::ffff:192.168.180.68:7001 :::*                        LISTEN      32015/java

殺掉佔用80端口的進程

② .kill -9 846

③ .如果前兩個方法不行的話，則重啓後再啓動httpd服務

2.Apache啓動失敗，httpd：httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName

① .進入apache的配置文件

?

1	vi /etc/httpd/conf/httpd .conf

② ./ServerName 查找ServerName

?

1	#ServerName www.example.com:80

將其前面的#去掉

:wq保存並退出

③ .重啓服務

?

1	systemctl restart httpd.service
